IMPROVEMENT IN CARPET-BEATERS.

Specificationforming part of Letters Patent No. 212,476, dated February18, 1879; application filed March 1, 1878.

To all whom "it may concern.-

Be it known that I, JESSE L. LEACH, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented a new and usefulImprovement in Machines for Cleaning Oarpets, which improvement is fullyset forth in the following specification and accompanying drawings, inwhich- Figure 1 is a top or plan view of the ma chine embodying myinvention. Fig. 2 is a transverse vertical section thereof in line m 00,Fig. 1. Fig. 3 is a rear View thereof.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention relates to improvements in carpet-cleaners, as hereinaftermore fully set forth and claimed.

Referring to the drawings, A represents a suitable frame for supportingthe parts of the machine, and to the sides of the same there isjournaled the revolving beater-shaft B.

0 represents the heaters, which are connected to the shaft B so as toswing therefrom, and consist of the flexible straps b and stocks a,which are hinged to the shaft B by means of staples, the said straps I)being secured in the stocks, and thereby re-enforced at their endsnearest to the shaft. As shown, these stocks are composed each of astrap doubled over so as to constitute aloop around a staple on theshaft, the two ends of the said strap being secured by rivets orstitching, or in an equivalent way, uponthe two sides of a strap, 1),thereby forming a stock which considerably stiffens up the end of theflexible strap.

To the shaft there are also connected staples D, which project from theface thereof, and they are arranged in proximity to the places ofconnection of the heaters.

Supported on the frame A, in line parallel with the shaft B, is a bed,E, which consists of elevated straps E, secured at their inner ends tothe frame of the bed, and passed over an elevating-bar, 67, mounted onthe side pieces of the frame A, the other or'outer ends of the strapsbeing properly secured.

E represents the depressed portion of the bed, which occupies a positionbelow the straps E, and is constructed of leather, rubber, or

other flexible material. On the upper face of the pad E, at the innerend thereof, or end on the side facing the beater-shaft, there aresecured pieces F, against which the straps E are in contact, forelevating said straps at the line nearest the heaters.

It will be seen that the beater-shaft is on nearly a horizontal linewith the bed. When the shaft rotates, the swinging heaters extend fromthe shaft, the stocks or arms standing at or about right lines, and thetips at a slight obtuse angle; consequently, when the heaters reach thebed they conform to its incline and deliver their blows flat, directlydownward, and sharp on the carpet, which is passed over the bed backwardand forward in any suitable manner, the blows being delivered below thehorizontal line, and above an "angle of, say, twenty degrees depression.tliy these means I overcome pulling or scu fray the ends of the carpet,and th e cut places which frequently exist at the sides of the carpet.

In many cases the width of the carpet is such that it occupies lessspace than the width of the bed; consequently certain heaters areuselessly and injuriously striking the pad. To

prevent this those heaters are folded or gathered, and secured by meansof the staples D, thus making said heaters inoperative.

In order to adjust the'tension of the straps E relatively to the textureor strength of carpets, I employ a roller, G, and attach the outer endsof said straps thereto.

By rotating the roller in one direction the straps will be tightened,and by a reversed movement the straps will be slackened. In the formercase carpets that are strong and in good order will be beaten or cleanedwhile suspended or resting on the elevated straps E, and in the lattercase the weight of the carpet and action of the heaters-will depress thecar pet on the pad, so that as it is not stretched it will be enabled toendure with safety the heatin g operation. Should the carpet hetemporarily withdrawn from the bed and the beater-shaft be in motion,the heaters will strike the depressed pad E without injury to themselvesor to the bed.

Having thus described my invention, what blows, which I claim as new,and desire to secure by Letters Patent, is

-1. The swingingbeaters C, composed of flexible straps secured to andstiffened by the stocks a at their inner ends, and pivoted to arevolving shaft, B, substantially as described, and for the purpose setforth.

2. The bed E, formed of a depressed pad, E, elevating-straps E, and adjListing-roller G, substantially as described, and for the purpose setforth.

3. The beater-shaft provided with beaters' O, composed of flexiblestraps with the stiffenin g-stocks a, and with the staples D, forsecuring the beaters when not in use, substantially as described.

.4. The pad E, provided with the pieces E,

in combination with the straps E and roller G, substantially asdescribed, and for the purpose set forth.

5. The adjusting-roller G, in combination with the elevating-straps E,bar d, and pad E, substantially as described, and for the purpose setforth.

' 6. The combination of the swinging heaters C, pivoted to a revolvingshaft, B, with the bed E, formed of a depressed pad, E, andelevating-straps E, substantially as described, and for the purpose setforth.
